Question

Chief anatomical feature of Cucurbitaceae family is

• A. Bicollateral vascular bundles
• B. Conjoint vascular bundle
• C. Radial vascular bundle
• D. None of the above

Answer 1

The correct option is A Bicollateral vascular bundles

Bicollateral vascular bundles contain two patches of phloem on either sides of the xylem on the same radius. The outer phloem or external phloem remains towards the periphery of the central cylinder and inner or internal phloem remains towards the centre.

Bicollateral vascular bundle is characteristic of plants in family Cucurbitaceae and Solanaceae. Thus, option A is correct.

Conjoint vascular bundle and radial vascular bundle are absent in Cucurbitaceae family.
